We are discussing a cross country ski route from Hwy 4, at the end of the plowed road, heading north and east. You ski east on 4, over Pacific Grade Summit, and down into the Hermit Valley. Then you leave 4 and head north through Deer Valley. Eventually you reach Blue Lakes, and you continue north on the Blue Lakes Jeep Road. That intercepts Hwy 88 a few miles east of Carson Pass at the Red Lake Turnoff. Due to the winter highways, it is best if you organize this with two ski groups going in opposite directions. One group starts on Hwy 4, and one group starts on Hwy 88. If weather is good, both groups meet to snow camp in Deer Valley, which is approximately the middle, and car keys can be exchanged. I've done it in each direction, but I prefer starting on Hwy 88. You also have to have a contingency plan that if the Deer Valley meeting doesn't happen, each group has to turn around and retrace tracks back to their own cars.
